Carbides of Y 5Si 3, of general formula Y 5Si 3C x , where x=0.05–0.7, have been prepared by arc melting and their reaction with hydrogen studied. Single-phase carbides can only be made melting pre-formed Y 5Si 3 with carbon. An activation process, which earlier work did not find, has been developed...
